Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Shown in reference picture 1, Fig. 2 and Fig. 3, the invention discloses a kind of heavy current disconnecting switches contact finger mechanism, including copper bar 7
And two pieces of supporting splints 1 of the upper and lower sides of copper bar 7 are disposed side by side on by rotating shaft 6, it is also connected between two described supporting splints 1
There is an axis of guide 3, two blocks of fingertip plates have been mounted opposite by height-adjustable I-shaped fixed hub 4 on the described axis of guide 3
8, two groups of fingertip plates 8 are symmetrically arranged on the both sides of copper bar 7 and ensure that the initial of fingertip plate 8 is opened away from the described axis of guide by fixed hub 4
Between 3 are fixedly connected on two pieces of supporting splints 1 by fastening bolt 5, described fingertip plate 8 is by fingertip fixed plate 8.2 and sets
Contact fingertip 8.1 at 8.2 positive both ends of fingertip fixed plate is formed, and contact fingertip 8.1 is riveted in fingertip fixed plate 8.2,
One or more semilune spring leafs 2 are provided between fingertip fixed plate 8.2 and supporting splint 1, spring leaf 2 is in fingertip fixed plate
Support force, fingertip fixed plate 8.2 and supporting splint 1 are provided between 8.2 and supporting splint 1 by semilune spring leaf reversing device branch
Support, is connected by the axis of guide 3, is then arranged on by supporting splint in rotating shaft 6, and fastening bolt 5 fastens, radially fixed, axial direction
Do not fix, can be opened according to the CCZT of copper bar 7 is whole away from size, so as to realize the Multi-contact of multiple fingertip plates 8 and copper bar 7.
